PIERSON STACKHOUSE, OF PINEVILLE, PENNSYLVANIA.

IMPROVEMENT IN BUTTER-WORKERS.

Specification forming part of Letters Patent No. 140,739, dated July 8, 1873; application led i April 21, 1873.

To all whom it may concern:

Be it known that I, PiERsoN M. S'rncie HOUSE, of Pineville, in the county of Bucks and State of Pennsylvania, have invented a new and useful Improvement in Butter-Workers; and I do hereby declare the following to be a clear and exact description of the nature thereof sufficient to enable others skilled in the art towhichmy invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings making part of this specification, in which- Figure l is a side elevation of the device embodying my invention. Fig. 2 is a top or plan view thereof. Fig. 3 is an end View thereof.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in a trough adapted to yield to the thickness of the butter during the Working operation, in combination with a uted roller for taking hold of and thoroughly working the butter. It also consists in a rack, which, operated by a pinion for advancing and returning the trough,is attached to the trough in sucha manner that the latter may be loW- ered and elevated.without-imparting corresponding movement to the trough. It also consists in straps so attached to the trough that the latter will receive longitudinal inotion` from the 'rack Without interfering with the yielding movements of said trough.

Referring to the drawings, A represents an open frame, which is mounted on legs or feet, and constitutes a table or stand. B represents a trough, which is fitted within the upper part of the stand or frame A, and rests on strips C, which are supported ou springs 1 D located on the side pieces E of the frame.

From the sides of the frame there rise standards F, which support the bearings Gr of a roller, H, which is iiuted or corrugated transversely, and is arranged over the trough B in close proximity thereto. The bearings G consist of vertical blocks, which are connected, by dovetail or other locking joints, to counterblocks secured to the standards F. J represents a longitudinally-arranged rack, which is rested on a side strip of the frame A, and is connected to the trough B by straps K,which are secured to the ends of the rack or rack-bar and attached loosely to the trough in such a manner as to permit the raising and lowering of the trough without imparting corresponding motion to the straps, and consequently to the rack. The rack is engaged by a pinion, L, which is keyed or otherwise secured to the axis of the roller H, and a crank-handle, M, is fitted ou said axis for necessary operation of parts. The strips on which the trough rests are inclined, so that said trough isinclined in its longitudinal direction in order to direct the butter milk to one end of the trough, where an opening will be formed, and beneath which a pan, pail, or other receptacle will be hung for gathering said milk. If desired, a leaf may be hinged to the side of the frame A. The bearings G'will be held 'verticallyl on the standards F by set-screws G properly applied, but the locking nature of the parts obviates fastenings of any kind to prevent horizontal movements. v

The operation is as follows: The butter is laid on the trough B, and the crank M so operated as to move, by means of rack and pinion, the trough in the direction opposite to the end receiving the butter, and advance the butter to the roller H. The roller rotates, and as the butter is presented thereto the `flutes or corrugations take hold of the butter and draw in, press, and work the same.

This operation is eased, and strain of the parts prevented, by the yielding of the trough.

During these movements the rack J has horizontal motion, but does not rise or fall, the

straps K being so attached to the trough that the latter has the same horizontal motion as the rack, but is permitted to rise and fall without regard to the rack. When the butter reaches the roller it cannot slip, but is caught by the Iiutes or corrugations and thoroughly compressed thereby.

lf desired, the trough B may be recipro- I cated so as to Work the butter on both movements thereof, or the butter may be run through in one direction only; but in either case the butter should be turned or moved so that the ridges constituting the flutes or cor rugations will not press into or work on the mass continually at the same spot, whereby the operation of working the butter will be thorough.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the vertically-yielding inclined trough B and the fluted roller H Working in connection therewith, in the manner and for the purposes described.

2. The rack J, in connection with the rising and fallin g trough B, substantially as and for the purpose set forth.

3. The straps K, in combination with the rack J and yielding trough B, when applied and operating as set forth.

The above signed by me this 19th day of.

April, 1873.
